Argonne research aims to improve nuclear fuel recycling and metal recovery
Servis
Scientists at Argonne National Laboratory are investigating a used nuclear fuel recycling technology that could lead to a scaled-down and more efficient approach to metal recovery, according to a recent news article from the lab. The research, led by Argonne radiochemist Anna Servis with funding from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), could have an impact beyond the nuclear fuel cycle and improve other high-value metal processing, such as rare earth recovery, according to Argonne.
The research: Servis’s work is being carried out under ARPA-E’s CURIE (Converting UNF Radioisotopes Into Energy) program. The specific project—Radioisotope Capture Intensification Using Rotating Packed Bed Contactors—started in 2023 and is scheduled to end in January 2026.

A shattered pellet injector based on in situ technology was installed on the HL-2A tokamak, and preliminary experiments were performed recently. In this paper, a fast current shutdown experiment introduces shattered pellet injection (SPI). In comparison with spontaneous disruptions and massive gas injection, SPI has advantages for disruption mitigation. The experimental results show the hard-X-ray radiation intensity (40 to 60 keV) rapidly falling from 20 to 0 when SPI is used. From this, we can infer that runaway electrons are suppressed. This observation indicates that SPI should be a good candidate for current fast shutdown in the future.
